22% of patients with moderate-to-severe ARDS develop acute cor pulmonale on protective ventilation. The right ventricle was never designed to handle pressure — and every PEEP increase, every hypercapnic minute, and every overdistended breath you deliver is loading a chamber that was built to fail...
The Henderson-Hasselbalch equation. Winter’s formula. The anion gap. The delta-delta ratio. The albumin correction. The osmolar gap. The Stewart approach. The strong ion difference. The strong ion gap. Compensation rules for every primary disorder. Mnemonics for every differential. This is the...
Why This Article Matters For more than 20 years, lung-protective ventilation has been synonymous with a single number: 6 mL/kg predicted body weight (PBW). This target has been taught, audited, benchmarked, and enforced across ICUs worldwide. Yet despite near-universal endorsement, real-world...
Why this article matters Critical illness triggers a profound, highly coordinated metabolic stress response that extends far beyond “hypercatabolism.” This comprehensive review reframes how we understand energy metabolism, nutrition, endocrine signaling, immune function, and recovery across the...
1. Why This Article Matters — Why You Should Read This Corticosteroids are everywhere in critical care. ARDS. Septic shock. COVID-19. Refractory hypoxemia. But when it comes to hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), their role remains controversial...
1. Why This Article Matters Invasive mechanical ventilation is the cornerstone of critical care. Yet, one major risk remains overlooked in daily practice: Ventilator exhaust can carry infectious aerosols, biofilm fragments, volatile anesthetics, and VOCs into the ICU environment — posing real risks...
